Description

Technical Field

[0001] This utility model relates to the field of ventilation therapy technology, and in particular to a connection device for preventing accidental removal of a breathing mask and a breathing mask. Background Technology

[0002] When worn, a breathing mask must remain stably in place on the user's face; when no longer needed, it must be easily and quickly removed from the user's face. In one existing type of breathing mask, the connecting parts between the headband and the mask body are separated when the headband is loosened. To re-secure the headband to the mask body, the connecting parts must be manually adjusted to reconnect them before a secure connection can be achieved, causing inconvenience for the patient. Utility Model Content

[0003] This utility model provides an anti-accidental removal connection device for a breathing mask and a breathing mask, which solves at least one of the above-mentioned technical problems.

[0004] This utility model provides an anti-accidental removal connection device for a breathing mask, including a first connection component for connecting to the headband of the breathing mask and a second connection component for connecting to the mask body of the breathing mask. The first connection component and the second connection component are magnetically attracted to each other in a first state.

[0005] The first connecting component and the second connecting component are further provided with a separation structure, which is configured to enable one of the first connecting component and the second connecting component to move to a second state relative to the other, thereby separating the first connecting component and the second connecting component from each other;

[0006] It also includes a reset component, which is connected to one of the first connection component and the second connection component, and the reset component is capable of restoring the first connection component or the second connection component to its initial state after the first connection component and the second connection component are separated from each other.

[0007] In one embodiment, the first connecting component is provided with a first magnetic attraction mechanism, the first magnetic attraction mechanism including a first magnet and a first magnetic attraction part located on the end face of the first connecting component;

[0008] The second connecting component is provided with a second magnetic attraction mechanism, which includes a second magnet and a second magnetic attraction part located on the end face of the second connecting component;

[0009] In the first state, the first magnet and the second magnetic attraction part attract each other, and / or the second magnet and the first magnetic attraction part attract each other.

[0010] In one embodiment, the first magnet and the second magnet have the same magnetic poles, and when the first connecting component and the second connecting component move relative to each other to a second state, the repulsive force between the first magnet and the second magnet is greater than the attraction force between the first magnet and the second magnetic attraction part and / or greater than the attraction force between the second magnet and the first magnetic attraction part.

[0011] In one embodiment, the first magnetic attraction part is a magnet or made of a magnetically attractable material, wherein when the first magnetic attraction part is a magnet, the magnetic poles of the first magnetic attraction part and the second magnet are opposite.

[0012] In one embodiment, the second magnetic attraction part is a magnet or made of a magnetically attractable material, wherein when the second magnetic attraction part is a magnet, the magnetic poles of the second magnetic attraction part and the first magnet are opposite.

[0013] In one embodiment, the first magnet and the second magnet have the same adsorption area, and / or the first magnetic attraction portion and the second magnetic attraction portion have the same adsorption area.

[0014] In one embodiment, the separation structure includes a rotating shaft disposed on one of the first connecting component and the second connecting component, and a limiting groove disposed on the other of the first connecting component and the second connecting component, the rotating shaft being rotatably disposed in the rotating groove.

[0015] In one embodiment, a reset component is further included, the reset component including an elastic element connected to a drive shaft and one of the first connecting component and the second connecting component, the drive shaft being fixed to the rotating shaft, the elastic element being configured to accumulate elastic potential energy when one of the first connecting component and the second connecting component moves relative to the other, and to release the elastic potential energy when one of the first connecting component and the second connecting component moves relative to the other to a second state.

[0016] In one embodiment, a rotational anti-slip part is further provided on the outer side of the first connecting component or the second connecting component.

[0017] In a second embodiment, the present invention provides a breathing mask, including the above-mentioned anti-misremoval connecting device for a breathing mask, and also includes a mask body and a headband, wherein the mask body and the headband are connected by the anti-misremoval connecting device.

[0018] In one embodiment, the number of the anti-accidental removal connecting devices is one or more. When the number of the anti-accidental removal connecting devices is multiple, two anti-accidental removal connecting devices are located on both sides of the mask body and are symmetrically arranged about the center of the mask body.

[0019] In one embodiment, the mask body is further provided with a receiving portion having an opening, the second connecting component is disposed in the receiving portion, and a portion of the second connecting component is exposed to the outside of the mask body through the opening.

[0020] Compared with the prior art, the advantage of this utility model is that after the first connecting component connected to the headband and the second connecting component connected to the mask body are separated, the reset component can restore the first connecting component or the second connecting component to the initial state, so that when the headband is fastened to the mask body again, the patient does not need to make manual adjustments, thereby improving the convenience of use.

[0021] Furthermore, the first and second connecting components are magnetically attracted to each other in the first state, ensuring a proper connection between the mask body and the headband. The separation structure allows one of the components to move relative to the other to the second state, separating them and facilitating easy and convenient removal of the mask body and headband from the user's face. Since the first and second connecting components are magnetically connected, applying external force directly to either component without the separation structure would require a significant force (at least enough to overcome the magnetic attraction). This force is far greater than the force exerted on the components by accidental contact or other misoperations. In other words, the force exerted on the components by accidental contact or other misoperations is insufficient to separate them, thus ensuring user safety in special scenarios such as nighttime use.

[0039] The present invention will be further described below with reference to the accompanying drawings.

[0040] like Figures 1-11 As shown, according to a first aspect of the present invention, the present invention provides an anti-accidental removal connection device for a breathing mask, comprising a first connection component 110 for connecting to the headband 103 of the breathing mask 100 and a second connection component 120 for connecting to the mask body 101 of the breathing mask 100, wherein the first connection component 110 and the second connection component 120 are mutually attracted in a first state (e.g., ...). Figures 1-4 (As shown).

[0041] The first connecting component 110 and the second connecting component 120 are further provided with a separation structure. The separation structure is configured to enable one of the first connecting component 110 and the second connecting component 120 to move to a second state relative to the other, thereby separating the first connecting component 110 and the second connecting component 120 from each other.

[0042] In some embodiments, the first connecting component 110 and the second connecting component 120 are configured to magnetically attract each other in the first state. Therefore, the first connecting component 110 and the second connecting component 120 are connected by an attractive force. If an external force is applied directly to the first connecting component 110 or the second connecting component 120 without a separation structure, a large separation force (e.g., greater than the attractive force between them) is required. This separation force is far greater than the force applied to the first connecting component 110 or the second connecting component 120 during accidental touches or other misoperations. In other words, the force applied to the first connecting component 110 or the second connecting component 120 during accidental touches or other misoperations is completely insufficient to separate them, thus ensuring user safety in special scenarios such as nighttime use.

[0043] Specifically, such as Figure 7 and Figure 8 As shown, a first magnetic attraction mechanism 115 is provided on the first connecting assembly 110. The first magnetic attraction mechanism 115 includes a first magnet 111 and a first magnetic attraction part 112 located on the end face of the first connecting assembly 110. Figure 5 , Figure 6 and Figure 9 As shown, a second magnetic attraction mechanism 125 is provided on the second connecting component 120. The second magnetic attraction mechanism 125 includes a second magnet 121 and a second magnetic attraction part 122 located on the end face of the second connecting component 120.

[0044] In this design, both the first magnet 111 and the second magnet 121 are magnets, but they share the same magnetic poles; for example, both may be S poles or both may be N poles. Therefore, when the first magnet 111 and the second magnet 121 approach each other until they contact (overlap), a repulsive force is generated between them. Furthermore, the adsorption areas of the first magnet 111 and the second magnet 121 (e.g., their pole surface areas) can be the same.

[0045] Furthermore, the first magnetic attraction part 112 can be a magnet or made of a magnetically attractive material, and the second magnetic attraction part 122 can be a magnet or made of a magnetically attractive material. The attraction areas of the first magnetic attraction part 112 and the second magnetic attraction part 122 can be the same, and the attraction area of ​​the first magnetic attraction part 112 can be larger than the attraction area of ​​the first magnet 111, and the attraction area of ​​the second magnetic attraction part 122 can be larger than the attraction area of ​​the second magnet 121; and vice versa.

[0046] When both the first magnetic attraction part 112 and the second magnetic attraction part 122 are magnets, the magnetic poles of the first magnetic attraction part 112 and the second magnet 121 are opposite, and the magnetic poles of the second magnetic attraction part 122 and the first magnet 111 are opposite. Therefore, it can be seen that the first magnet 111 can attract the second magnetic attraction part 122, and the second magnet 121 can attract the first magnetic attraction part 112.

[0047] When both the first magnetic attraction part 112 and the second magnetic attraction part 122 are made of magnetically attractive materials, the first magnet 111 can attract the second magnetic attraction part 122, and the second magnet 121 can attract the first magnetic attraction part 112.

[0048] Alternatively, if one of the first magnetic attraction part 112 and the second magnetic attraction part 122 is a magnet, and the other is made of a magnetically attractive material, then, if the first magnetic attraction part 112 is a magnet and the second magnetic attraction part 122 is made of a magnetically attractive material, the magnetic poles of the first magnetic attraction part 112 and the second magnet 121 are opposite. This allows the first magnet 111 to attract the second magnetic attraction part 122, and the second magnet 121 to attract the first magnetic attraction part 112. The situation is similar if the second magnetic attraction part 122 is a magnet and the first magnetic attraction part 112 is made of a magnetically attractive material, and therefore will not be described further.

[0049] When the first connecting component 110 and the second connecting component 120 are in the first state, the first connecting component 110 and the second connecting component 120 are arranged opposite to each other, and the surfaces of the first magnetic attraction mechanism 115 and the second magnetic attraction mechanism 125 are arranged opposite to each other and in contact. Specifically, the first magnet 111 of the first magnetic attraction mechanism 115 attracts the second magnetic attraction portion 122 of the second magnetic attraction mechanism 125, and / or the second magnet 121 of the second magnetic attraction mechanism 125 attracts the first magnetic attraction portion 112 of the first magnetic attraction mechanism 115 (please refer to...). Figure 8 This allows the first connecting component 110 and the second connecting component 120 to be magnetically fixed together.

[0050] It should be noted that the attraction between the first magnet 111 and the second magnetic attraction part 122 and / or the second magnet 121 and the first magnetic attraction part 112 can be set to be large in order to avoid accidental contact that could cause them to separate.

[0051] Furthermore, the first magnet 111 and the second magnet 121 have the same magnetic poles; for example, both the first magnet 111 and the second magnet 121 are S poles or both are N poles. Therefore, when one of the first connecting assembly 110 and the second connecting assembly 120 moves relative to the other to the second state (e.g., ... Figure 5 As shown, the repulsive force between the first magnet 111 and the second magnet 121 is greater than that between the first magnet 111 and the second magnetic attraction part 122 and / or greater than that between the second magnet 121 and the first magnetic attraction part 112.

[0052] For example, when the second connecting component 120 moves relative to the first connecting component 110, the second magnet 121 on the second connecting component 120 also moves relative to the first magnet 111 on the first connecting component 110. That is, the first magnet 111 and the second magnet 121 begin to approach each other until a part (or all) of the two come into contact (overlap). At this point, the repulsive force between the two is greater than the attractive force between the first magnet 111 and the second magnetic attraction part 122 and between the second magnet 121 and the first magnetic attraction part 112, thereby separating the first connecting component 110 and the second connecting component 120.

[0053] More specifically, when the second magnet 121 on the second connecting assembly 120 moves relative to the first magnet 111 on the first connecting assembly 110 until the first magnet 111 and the second magnet 121 come into contact with each other, as the second connecting assembly 120 moves further, the contact area between the first magnet 111 and the second magnetic attraction part 122 and the contact area between the second magnet 121 and the first magnetic attraction part 112 further decreases; conversely, the contact area between the first magnet 111 and the second magnet 121 further increases. When the contact area between the first magnet 111 and the second magnet 121 is greater than 1 / 2 of their own area, the repulsive force between them can be greater than the attractive force between the first magnet 111 and the second magnetic attraction part 122 and between the second magnet 121 and the first magnetic attraction part 112, thereby separating the first connecting assembly 110 and the second connecting assembly 120.

[0054] like Figure 5 As shown, and please refer to Figure 8The separation structure includes a rotating shaft 123 disposed on one of the first connecting assembly 110 and the second connecting assembly 120, and a limiting groove 113 disposed on the other of the first connecting assembly 110 and the second connecting assembly 120, wherein the rotating shaft 123 is rotatably disposed in the limiting groove 113.

[0055] For example, a rotating shaft 123 passes through and is fixedly connected to the second connecting assembly 120. The rotating shaft 123 is located at the center of the second connecting assembly 120 and extends along the axial direction of the second connecting assembly 120. A limiting groove 113 is provided at the center of the first connecting assembly 110, which is coaxially arranged with the rotating shaft 123, and the rotating shaft 123 is rotatably disposed in the limiting groove 113. Therefore, the second connecting assembly 120 drives the rotating shaft 123 to rotate relative to the first connecting assembly 110 in the limiting groove 113. When the second connecting assembly 120 rotates to the point where the repulsive force between the first magnet 111 and the second magnet 121 is sufficiently large, the first connecting assembly 110 and the second connecting assembly 120 can be separated. Therefore, it can be understood that the second magnet 121 and the second magnetic attraction part 122 are arranged circumferentially along the rotating shaft 123, and correspondingly, the first magnet 111 and the first magnetic attraction part 112 are also arranged circumferentially along the rotating shaft 123. Further, as Figure 9 , Figure 10 and Figure 11 As shown, the anti-misconnection device also includes a reset component 130. The reset component 130 includes an elastic element 132. The elastic element 132 is connected to the drive shaft 133 and one of the first connecting component 110 and the second connecting component 120. The elastic element 132 is configured to accumulate elastic potential energy when the first connecting component 110 and the second connecting component 120 move relative to each other, and to release the elastic potential energy when the first connecting component 110 and the second connecting component 120 move relative to each other to the second state.

[0056] like Figure 9 As shown, the drive shaft 133 can be fixedly connected to the rotating shaft 123. The elastic element 132 can be, for example, a coil spring, which is wound around the drive shaft 133. One end of the elastic element 132 is fixed to the drive shaft 133, and the other end is fixed to the second connecting assembly 120. Therefore, when a torque is applied to the second connecting assembly 120 to make it rotate, it drives the rotating shaft 123 and the drive shaft 133 to rotate, thereby allowing the elastic element 132 to be wound more tightly on the drive shaft 133, that is, the elastic element 132 accumulates elastic potential energy (e.g., Figure 11 (as shown); when the torque on the second connecting assembly 120 is removed, the elastic element 132 releases its elastic potential energy and is wound more loosely on the drive shaft 133, thus allowing the second connecting assembly 120 to rotate in the opposite direction back to its initial state.

[0057] like Figure 6 and Figure 9 As shown, a rotational anti-slip portion 124 is located on the outer side of the first connecting assembly 110 or the second connecting assembly 120. The rotational anti-slip portion 124 may be, for example, an anti-slip groove, anti-slip strip, or anti-slip protrusion provided on the outer wall of the first connecting assembly 110 or the second connecting assembly 120, serving to prevent slippage and allowing the user to apply torque to the first connecting assembly 110 or the second connecting assembly 120, thereby causing the first connecting assembly 110 or the second connecting assembly 120 to rotate.

[0058] like Figure 9 As shown, the second connecting assembly 120 can be connected to the mask body 101 via a rotating shaft 123. Figure 7 and Figure 3 As shown, a connecting structure 114 is provided at one end of the first connecting component 110 away from the first magnetic attraction mechanism 115. The connecting structure 114 can be a connecting groove, a buckle, or other structure. The first connecting component 110 can be connected to the headband 103 through the connecting structure 114.

[0059] In use, such as Figure 5 and Figure 8 As shown, the first connecting component 110 and the second connecting component 120 are attracted to each other. The first magnet 111 of the first magnetic attraction mechanism 115 and the second magnetic attraction part 122 of the second magnetic attraction mechanism 125 attract each other. The second magnet 121 of the second magnetic attraction mechanism 125 and the first magnetic attraction part 112 of the first magnetic attraction mechanism 115 attract each other. If it is necessary to separate the first connecting component 110 and the second connecting component 120, the user can apply torque to the second connecting component 120 by rotating the anti-slip part 124, so that the second connecting component 120 rotates clockwise or counterclockwise until the repulsive force between the first magnet 111 and the second magnet 121 is large enough, and then the first connecting component 110 and the second connecting component 120 can be separated.

[0060] Understandably, the angle of rotation of one of the first connecting components 110 and the second connecting component 120 relative to the other should be within 180°. That is, when the rotation angle of the second connecting component 120 is within 180°, the repulsive force between the first magnet 111 and the second magnet 121 can separate the first connecting component 110 and the second connecting component 120, thereby making it more convenient for the user to adjust.

[0061] According to a second aspect of this utility model, a breathing mask 100 is provided, including the aforementioned anti-accidental removal connection device for the breathing mask. For example... Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the breathing mask 100 also includes a mask body 101 and a headband 103, which are connected by an anti-misremoval connection device.

[0062] The mask body 101 may be in the form of a full-face mask, a nose mask, or a mouth and nose mask. A sealing part 102 is provided on its inner side (i.e. the side closer to the user) for contact with the user's face. The headband 103 is used to fix the mask body 101 to the user's face.

[0063] The number of anti-accidental removal connecting devices is one or more. When there are multiple anti-accidental removal connecting devices, two of them are located on both sides of the mask body 101 and are symmetrically arranged about the center of the mask body 101.

[0064] like Figure 2 and Figure 3 As shown, there are two anti-accidental removal connecting devices, located on opposite sides of the mask body 101 and symmetrically arranged about the center of the mask body 101. Therefore, the second connecting component 120 in the anti-accidental removal connecting device on the left side of the mask body 101 can rotate counterclockwise, conforming to the convention for left- and right-handed operation.

[0065] like Figure 9 As shown, the mask body 101 is also provided with a receiving portion 104 having an opening 105, the second connecting component 120 is disposed in the receiving portion 104, and a part of the second connecting component 120 is exposed to the outside of the mask body 101 through the opening 105.

[0066] like Figure 9 As shown, the end of the rotating shaft 123 away from the second connecting assembly 120 is rotatably connected to the mask body 101. The second connecting assembly 120 is located in the receiving portion 104. A portion of the second connecting assembly 120 is exposed to the outside of the mask body 101 through the opening 105 so that the user can apply torque to the second connecting assembly 120 at the opening 105.

[0067] The included angle between the two sidewalls of the opening 105 can be 60° or more, allowing the user to expose at least one finger to the outside of the mask body 101 to apply torque to the second connecting assembly 120.

[0068] As shown above, the second connecting component 120 is connected to the mask body 101 via the rotating shaft 123, and the first connecting component 110 is connected to the headband 103 via the connecting structure 114. Therefore, when the breathing mask 100 is worn on the user's face, the first connecting component 110 and the second connecting component 120 attract each other in the first state, which can fix the breathing mask 100 on the user's face. When it is necessary to remove the breathing mask 100, the second connecting component 120 on the left and / or right sides of the mask body 101 can be rotated counterclockwise / clockwise until the repulsive force between the first magnet 111 and the second magnet 121 is large enough, so that the first connecting component 110 and the second connecting component 120 can be separated, thereby removing the breathing mask 100 from the user's face.

[0069] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
